9/10. Terrific episode. Brilliant set, and beautifully filmed. Viewing this episode it's hard to imagine it was filmed only a few months after season 2, as it looks so ahead of it's time. As do many season 3 episodes. While there are some good episodes in season 2, they do look very dated when compared to the following season. Rich.

It's a great episode, one of my favourite Cathys. Nice and tense, and lots of great moments for both Steed and Cathy. And what's not to love about a boss named DISCO? _________________Last Watched:Who Was That Man I Saw You With?

Aw, thanks! This episode originally made me a bit uncomfortable (as do all "Steed's a traitor" episodes), but it really is one of Season 3's best. It also kind of made me hate the Ministry._________________"It's a conflict of science and humanity! Equations, isotherms...I have a dynamic too."

Yeah, the Ministry comes across as quite dark in this episode, it's an interesting touch. You don't want to get on the wrong side of it. The Wringer has the same quality and it's also there in Man With Two Shadows.
